Sec. 74.1283  Station identification.

    (a) The call sign of an FM broadcast translator station will consist 
of the initial letter K or W followed by the channel number assigned to 
the translator and two letters. The use of the initial letter will 
generally conform to the pattern used in the broadcast service. The two 
letter combinations following the channel number will be assigned in 
order and requests for the assignment of particular combinations of 
letters will not be considered.
    (b) The call sign of an FM booster station will consist of the call 
sign of the primary station followed by the letters ``FM'' and the 
number of the booster station being authorized, e.g., WFCCFM-1.
    (c) A translator station authorized under this subpart shall be 
identified by one of the following methods.
    (1) By arranging for the primary station whose station is being 
rebroadcast to identify the translator station by call sign and 
location. Three such identifications shall be made during each day: once 
between 7 a.m. and 9 a.m., once between 12:55 p.m. and 1:05 p.m. and 
once between 4 p.m. and 6 p.m. Stations which do not begin their 
broadcast before 9 a.m. shall make their first identification at the 
beginning of their broadcast days. The licensee of an FM translator 
whose station identification is made by the primary station must arrange 
for the primary station licensee to keep in its file, and to make 
available to FCC personnel, the translator's call letters and location, 
giving the name, address and telephone number of the licensee or his 
service representative to be contacted in the event of malfunction of 
the translator. It shall be the responsibility of the translator 
licensee to furnish current information to the primary station licensee 
for this purpose.
    (2) By transmitting the call sign in International Morse Code at 
least once each hour. Transmitters of FM broadcast translator stations 
of more than 1 watt transmitter output power must be equipped with an 
automatic keying device that will transmit the call sign at least once 
each hour, unless there is in effect a firm agreement with the 
translator's primary station as provided in Sec. 74.1283(c)(1) of this 
section. Transmission of the call sign can be accomplished by:
    (i) Frequency shifting key; the carrier shift shall not be less than 
5 kHz nor greater than 25 kHz.
    (ii) Amplitude modulation of the FM carrier of at least 30 percent 
modulation. The audio frequency tone use shall not be within 200 hertz 
of the Emergency Broadcast System Attention signal alerting frequencies.
    (d) FM broadcast booster stations shall be identified by their 
primary stations, by the broadcasting of the primary station's call 
signs and location, in accordance with the provisions of Sec. 73.1201 of 
this chapter.

    (e) The Commission may, in its discretion, specify other methods of 
identification.
